ALEXANDER LEVETT, OF NEW YORK, N. Y'.

POLISHING COMPOSITION.

SPECIFICATION forming part of Letters Patent No. 246,958, dated September 13, 1881,

' Application filed July 26, 1881. (No specimens.)

into frames or forms and allowed to cool. In

use this composition is held to the polishingwheel until enough has adhered thereto for the purpose in hand. This combination forms a convenient compound for holding together the polishing materials and causing them to adhere to the wheel. The objection to it is the expense of the base, which serves little or no good purpose for polishing and is needed chiefly as a vehicle.

My polishing composition consists of any of the materials usually employed for polishing, and has for its base or vehicle the products obtained by the action of acids or ferments upon starch, commonly known as glucose or grape-sugar. For this purpose it should contain not to exceed fifteen per centum of dextriue, and may contain less when it is desired to have it harder than usual, as in very warm weather.

The glucose or grape-sugar is placed in a suitable vessel and melted, the polishing material desired is added thereto in such proportions as may be desired, and the ingredients are then stirred until they thoroughly combine. The composition is then poured out into molds and allowed to cool, when it is ready for use.

This composition possesses all the desirable qualities of those heretofore known, and when cold and not in use is not sticky, and at the sametime when held to the wheel it is quickly warmed by the friction, and is much more adhesive to the wheel than any of the compositions heretofore known.

What I claim, and desire to secure by Letters Patent, is

The polishing composition described, consisting of polishingmaterials and a base or vehicle of the products obtained by the action of acids or ferments upon starch.

ALEXANDER LEVETT.
